How often do you pump up your tyres on tour
Recently whilst touring, with a friend, I noticed that every 2 days I had to pump my 700x 28 back up to 8 bars, 120psi, whilst my friend riding on 700x 32 had to pump up his tyres every 4-5 days. His tyres went to max 6 bars, 80 psi. I carry approx 15 kg whilst touring and his weight was about the same. I just wonderes if wider tyres needed less filling up then the narrower tyres.
